Federal agent Charlie Houser is forced to fight gun crime with a meager tool: a bunch of boxes of paper.

Just read this whole thing so you can understand what malevolent evil bastards the gun lobby and their political prostitutes in (mostly) the GOP are:

There's no telling how many guns we have in America—and when one gets used in a crime, no way for the cops to connect it to its owner. The only place the police can turn for help is a Kafkaesque agency in West Virginia, where, thanks to the gun lobby, computers are illegal and detective work is absurdly antiquated. On purpose. Thing is, the geniuses who work there are quietly inventing ways to do the impossible.

You just will not believe it. They don't want law enforcement to have the ability to trace guns. None.
